Field of application
The iTHERM TMS31 is a versatile, modular multipoint temperature assembly designed for temperature average detection and profiling in grain, organic bulk material storage silos and in oil, fuel storage tanks.
The device’s mechanical robustness and accurate temperature sensors offer the necessary characteristics for safe, reliable and economic product storage operations. In its standard configuration it is available with up to 20 thermocouple (TC) or RTD sensors fitted to a primary metal rope.
Oil storage tanks
Bulk material silos
Benefits
